There
are some evils in the universe that need to be fought. And others that need
redeeming...

Many years ago The Doctor, a student at
the Academy on Gallifrey, lost a friend
to the mysterious and malevolent force
known as The
Celestial Toymaker. Now, in his fifth
incarnation, The Doctor receives a telepathic
call from his long-lost classmate, begging
for help.

As he sets out to rescue his friend and exact revenge, The Doctor's companions become increasingly involved. Adric,
determined to justify his place aboard the TARDIS, opts to face the
Toymaker's game challenges while
Nyssa, angered by The Doctor's actions,
finds herself excluded by the people she thought were her friends.
And what is the connection between the Toymaker
and the planet Dymok, whose comatose inhabitants
find a new saviour in the shape of Tegan
Jovanka?
